Copper monosulfide - Wikipedia
Copper monosulfide is a stone compound of copper and sulfur.It occurs in nature as the dark indigo blue mineral covellite.It is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H 2 S, is bubbled through solutions of Cu(II) salts. It is one of a number of binary compounds of copper and sulfur (see copper sulfide for an overview of ...

Copper Sulfide - an overview | ScienceDirect Topics
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide ...

Copper(II) sulfide | CuS - PubChem
The carcinogenicity of cupric oxide, cupric sulfide, and cuprous sulfide in 2 to 3 month old Wistar rats /was studied/. Groups of 30-32 rats were given single im injections containing 20 mg of cupric oxide (16 mg copper), cupric sulfide (13.3 mg copper), and cuprous sulfide (16 mg copper) into the left and the right thigh of each rat.All animals were observed for up to 20 months, after which ...
Copper sulfide | Exhibition chemistry | RSC …
The copper wire reacts readily with the hot sulfur gas (S 8, S 4 and S 2), forming a dark grey, brittle crystalline solid of copper sulfide. After ca five minutes of heating, carefully remove the hook and copper sulfide using tongs and allow any excess sulfur to burn, thus cleaning the copper sulfide. Allow to cool and re-weigh the copper ...

The Mineral Gallery - Sulfides Class
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
Copper Sulfate Uses - Science Struck
Copper sulfate can be prepared in the laboratory by reacting various compounds of copper (II) with sulfuric acid. However, it is commercially available on a large-scale basis, and is an economic source of Cu. Copper sulfate pentahydrate readily dissolves in water and is also soluble in methanol, glycerol, and to some extent in ethanol. When the blue crystals of copper sulfate are heated in an ...

The failure involved sulfide contamination of the copper conductor and copper sulfide in the associated stone insulation in the upper third portion of the failed winding. The theory is put forth that a combination of time and temperature and corrosive sulfur in the oil created conditions to exist in the transformer that caused this problem despite the oil having passed the standard test ...
Hydrogen sulfide attack and corrosion of copper …
While not a normal component of air, hydrogen sulfide will really tarnish copper rapidly forming one or more forms of copper sulfide. Hydrogen ions are positive and normally would not react with copper. Acids are a special exception. The other normal gasses (in air) that could be negative ions are not reactive under normal conditions. High heat can change that. James Watts - Navarre, Florida ...
